Baumann 24000CVF Valve with SV Electric Actuator
Management of Change
Management of Change (MOC) is a procedure used to proactively manage changes
that can potentially affect safety or general procedure within a process plant. Product
changes often have a signicant impact on plant efciency throughout the transition
period. In lieu of the complexity of completing an MOC approval process, this
MOC Guide has been developed to prevent delays and difculties while ensuring a
successful product change.
Contained in the following sections are design comparisons between the obsolete
Baumann NV electric actuator and the current Baumann SV electric actuator. These
comparisons are intended to help end-users complete MOC approval documents to
understand the similarities and differences between the Baumann NV and SV electric
actuators to facilitate a safe and efcient transition to the Baumann SV electric actuator.
Background
The Baumann NV electric actuator series has been used with Baumann sliding stem
control valves for a number of years. It was used for temperature and humidity
control for HVAC applications including: hot and chilled water, steam, and glycol;
semiconductor manufacturing applications, including: clean rooms, make-up air
handlers, recirculation air handlers, humidication, chillers, jackets, and glycol
systems; along with many other industrial environments, including but not limited
to textiles, food and beverage, and tire manufacturing. The Baumann NV electric
actuator series is now an obsolete product and is to be directly replaced with the
Baumann SV electric actuator series.

The Baumann SV electric actuator series leverages features end-users have come to
know in the NV actuator, along with improvements like increased output thrust, a
lighter weight assembly, and faster stroke speed.
Question & Answer Checklist
Q: Does the proposed modication cause any changes to the piping and
1

instrumentation diagram (P&ID)?
A: No. Actuation mounting is the same for both the NV and the SV.
Q: Does the proposed modication change process chemistry,
technology, or operating and control philosophies?
A: No.
Q: Does the proposed modication change how the existing plant is
operated?
A: No. Valve capacity is not affected by actuator revisions.
2
Q: Does the proposed modication change process ows?
4
A: No. Valve capacity is not affected by actuator revisions.
Q: Does the proposed modication change existing pressure relief cases?
5
A: No. This change involves actuators only. Pressure relief valve sizing
is not considered when sizing and selecting Fisher control valves for
end user applications. If the control valve is determined to affect
upstream or downstream safety relief cases, review by the end user or
third party is recommended.
Q: Does the proposed modication change the process description?
6
A: No.
Q: Have the codes and standards to which the new equipment was
7
designed changed?
A: Not to our knowledge. Since both the Baumann NV and SV electric
actuators are buyout components, Fisher cannot conrm whether or
not our supplier’s design codes and standards have changed.

Q: Does the proposed modication change the materials of construction,

10
such as a change in material form (cast, forged, or alloy)?
A: Yes. The NV housing is polycarbon and the yoke is epoxy-coated
ductile iron, while the SV housing is die-cast aluminum with an
aluminum yoke.
Q: Does the proposed modication introduce new equipment items that
require periodic predictive maintenance?
A: No. The new equipment items will require the same periodic
maintenance as required by the old equipment items.
Q: Does the proposed modication change existing operator training
requirements?
A: No.
